Non- Euclidean calculus and quantum physics are enough to stretch any brain; and when one mixes them with folklore, and tries to trace a strange background of multi-dimensional reality behind the ghoulish hints of Gothic tales and the wild whispers of the chimney-corner, one can hardly expect to be wholly free from mental tension. (Dreams In The Witch-House)
The moon is dark, and the gods dance in the night; there is terror in the sky, for upon the moon hath sunk an eclipse foretold in no books of men or of earth's gods.
The monotony of a long heroic poem may often be pleasantly relieved by judicious interruptions in the perfect successions of rhymes, just as the metre may sometimes be adorned with occasional triplets and Alexandrines.
When I say that I can write nothing but weird fiction, I am not trying to exalt that medium but am merely confessing my own weakness.

The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents... some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new Dark Age.
With five feeble senses we pretend to comprehend the boundlessly complex cosmos, yet other beings with wider, stronger, or different range of senses might not only see very differently the things we see, but might see and study whole worlds of matter, energy, and life which lie close at hand yet can never be detected with the senses we have.
I expect nothing of man, and disown the race. The only folly is expecting what is never attained; man is most contemptible when compared with his own pretensions. It is better to laugh at man from outside the universe, than to weep for him within.
There be those who say that things and places have souls, and there be those who say they have not; I dare not say, myself, but I will tell of The Street.
